DUTCH Test (Dried Urine Test for Comprehensive Hormones)
Definition
The DUTCH test, developed by Precision Analytical, collects dried urine on filter paper at multiple time points across a 24-hour period. It measures estrogen (estradiol, estrone, estriol) and their metabolic pathways (2-OH, 4-OH, and 16-OH metabolites — each with distinct health implications), progesterone and its metabolites, testosterone and DHEA, and the full cortisol curve including the cortisol awakening response (CAR). Unlike a blood draw — which captures a single snapshot at one point in time — the DUTCH test captures daily hormone production, metabolic processing, and cortisol patterns. Knowing not just how much estrogen is present but how it is being metabolized is clinically important: 4-OH estrogen metabolites, for example, are associated with higher DNA damage risk compared to 2-OH metabolites. The test also includes organic acid markers for B vitamin status and neurotransmitter metabolism.
Frequently Asked Question
Why DUTCH Test (Dried Urine Test for Comprehensive Hormones) Matters
How Spokmed Company Uses It
Michelle Middleton, PA-C uses the DUTCH test as a key diagnostic tool when evaluating hormone-related symptoms in perimenopause, menopause, and related conditions. The full cortisol curve informs adrenal function and stress physiology. Estrogen metabolite ratios guide hormone therapy formulation decisions. The DUTCH test is used to establish baseline, guide protocol design, and monitor response to hormone therapy over time.
